Abstract
The invention provides a dispersion dye printing ink. The printing ink is of water soluble microcapsule shape which comprises a core material containing dispersion dye and alternative additive and a wall material which is made of at least one of the following materials, octenyl succinic acid modified starch, carrageenan, chitin, gelatin, guar gum, pectin, tamarindus polysaccharide gum and printing paste and alternative CMS material. The selective wall material components consists of printing paste, octenyl succinic acid modified starch and alternative CMS. The core material is wrapped by the wall material. The invention further provides printing ink preparation method and cold transferring printing method for application of the printing ink.
Description
Technical field
The disperse dyes printing ink that the present invention relates to use in the dyeing industry and its production and application, be specifically related to a kind of cold-transfer printing microcapsule disperse dye printing-ink.
Background technology
Transfer printing is the well-known a kind of printing method of dyeing industry, and it is earlier with printing process the pattern of stamp to be wanted in suitable dye ink printshop on the paper that special type was handled, and processes transfer printing paper (abbreviation transfer paper).After this, again with the one side of band printing ink on this transfer paper and by seal fabric driving fit, through heat and pressure, promptly subliming method makes dye sublimation impel ink lay to peel off from paper, with the pattern transfer on the transfer paper to fabric.This type transfering printing technology is widely used; But this distillation formula transfer printing (pressure sintering) has its shortcoming and limitation; Very narrow like the dye selection face; Tradition dispersed dye distillation transfer method; Because the distillation of dyestuff is shifted, dyeing behavior is relevant with molecular weight, molecular size, chemical structure, substituting group, polarity, tansition temperatures distillation pressure, the factors such as velocity of diffusion, dye saturation value and inorganic nature/organic value of dyestuff in fiber down of dyestuff, mostly adopts the structure dyestuffs (most is azo group) such as azo, nitro, anthraquinone of small molecular weight, low temperature modification; Such dyestuff contains aromatic amine and other carcinogenic substance all through the azo processing.In addition, because during general subliming method transfer printing, the dyestuff of transferring on the fabric from transfer paper can not all absorb fibrous inside, always some dyestuff remains in fabric face, becomes the relatively poor reason of transfer printing fabric fastness.Secondly because subliming method heat transfer printing printing ink all adopts the solvent preparation, to the very big difficulty of regenerated using existence of discarded transfer paper, environmental pollution is serious when producing transfer paper.
To existing the problems referred to above of traditional subliming method transfer printing of disperse dyes printing ink, the seventies in 20th century, developed the disperse dyes printing ink of micro encapsulation.So-called microencapsulation technology is wrapped in tiny dyestuff drop in the macromolecule membrane exactly, processes the microcapsule of diameter very little (below 500 microns).In the transfer printing process,,, the dyestuff and the auxiliary agent that are wrapped are discharged, thereby reach the transfer effect of expection because of breaking or diffusion through microcapsule wall of microcapsule through stimulations such as external pressure, friction, pH values.For example, Japanese Hayashi chemical company develops the micro-encapsulation disperse dyes printing-ink, is applied to polyester, polyester-cotton blend, acrylic fibers, polymeric amide and wool, obtains multicolour effect.It is encapsulated that Japan woods chemical industrial company with water is with dispersed dye that solvent carries out, and makes MCP-T type hydrophobicity micro-encapsulation disperse dyes printing-ink, when the dyestuff in the capsule after fiber migration and set, demonstrate fine snowflake particulate state color.Donghua University has developed a kind of methods for making and using same of disperse dyes printing ink of micro encapsulation; Wherein, adopt polyisocyanate compound or melamine resin prepolymer and vinyl monomer polyester piece good to be carried out and conventional HTHP open width dyeing, HTHP rope dyeing, thermosol dyeing or the repeatedly transfer printing that is close (referring to Chinese patent number 03116242.8,03116243.6 and 03116244.4) as the microcapsule disperse dye of microcapsule wall material.But for the dyeing of the current microcapsule disperse that is adopted usually, need under the high-temperature pressure dyeing condition, carry out, can't be applied to water-soluble is the cold-transfer printing technology (under the normal temperature condition) of jump condition.
Summary of the invention
In order to overcome in the existing transfering printing technology because of adopting traditional dispersed dye and the existing shortcoming of distillation transfer method, the contriver has carried out intensive research, has developed a kind of pure water miscible microcapsule disperse; Its adoptable dispersed dye chromatogram surmounts the category of low temperature modification, from the anthraquinone class, and the azo class; Common dyes such as heterocyclic are to nitrodiphenylamine, methine or vinylbenzene (Methine or Styryl), quinoline phthalein ketone (Quinohthalone); Ketoamine, tonka bean camphor (Counmarin) etc.Chromatogram is wide, and colour gamut is big, and colour system is complete, can in so big category, select thickening agent that is fit to the REACH of European Union standard and anti-high Exposure to Sunlight thickening agent for use fully.
When disperse dyes printing ink of the present invention was used for transfering printing process, externally pressure rubbed, and pH value etc. stimulate down, and microcapsule break or microcapsule wall spreads, and the dyestuff and the auxiliary agent that are wrapped are discharged, thereby reach the transfer effect of expection.This technology helps the dispersed dye of hydrophobic type and peels off transfer from the transfer printing paper substrate, helps water saving, and is energy-conservation, belongs to the printing technology of environment-friendly type, and technology is simple, and the pattern fineness is high.And because the present invention does not adopt heat energy distillation means, and only break the capsule transfer with pressure through moistening, and realize core-dispersed dye to dying on the fabric, therefore Fabric Style is not brought damage, can be applicable to the fabric of all kinds of top grades.
